I have 5 Solanum Jasminoides, which include 4 on a west facing balcony and one down in the garden. They were purchased at Armstrong Nursery in Santa Monica and originated at Monrovia in one gal containers. They're now in 16-18in containers and had been doing beautifully, until the leaves began turning dark purple-blackish looking. What could be causing this, and what's the solution? By the way, one of the plants still looks okay. I have someone who services my plants weekly. What seems to be missing here? Thanks for any information. Laura Blum Beverly Hills, CA |
